Clean Energy Regulator · data to September 2026

Rooftop solar and home batteries across Australia

Data to Sep 2026. Oct 2025 onward is provisional.

Why recent months are provisional

Installations can be registered with the Clean Energy Regulator up to 12 months after they happen, so figures from Oct 2025 onward will rise as late registrations arrive; earlier months can also be revised. A month-to-month difference is not the number of new systems installed in that month.

Small-scale solar systems and home batteries registered with the Clean Energy Regulator (CER) in Australia: how many, how much capacity and how it changed.

National figures on this site are the sum of the CER postcode rows for every valid postcode (postcode 0000, which the CER uses for invalid entries, is excluded). They are not an official CER national total.

Cumulative solar installations, AustraliaMonthly, January 2011 to September 2026; the line starts from the 283,307 installations of 2001–2010. Dotted, on the shaded band: provisional months from October 2025.

The last 12 months

Each spoke is one month of solar installations; the thin line on it is the same month a year earlier. A month-to-month difference is not the number of new systems installed in that month.

Sources and notes

Independent site Australia Solar & Battery Atlas is an independent site. It is not a government website and is not affiliated with the Clean Energy Regulator.

Coverage, symbols, caveats and source files

Coverage. 2,810 postcodes with CER solar records across Australia. Suburb names are not in the CER files and are not shown.

  • Provisional May still be revised; outlined, not filled.
  • Not collected The source did not collect this; grey.
  • Not published No value released for this cell; a gap, never zero.

Things to know

  • Months from October 2025 are provisional: installations can be registered up to 12 months late, so these figures will rise.
  • The CER publishes battery figures by postcode from July 2025. Earlier months show “Not collected”, never zero.
  • An installation can be a new system, an extension or a replacement, so counts are not the number of homes with solar.
